Energetic approach to gradient plasticity

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2010
AbstractWe formulate a problem of the evolution of elasto‐plastic materials subjected to external loads in the framework of large deformations and multiplicative plasticity. Our model includes gradients of the plastic strain and of hardening variables. We prove the existence of the so‐called energetic solution.

On elastic and plastic length scales in strain gradient plasticity

Structural Engineering and Mechanics, 2017
The Fleck-Hutchinson theory on strain gradient plasticity (SGP), proposed in Adv. Appl Mech 33 (1997) 295, has recently been reformulated by adopting the strategy of decomposing the second order strain presented by Lam et al. in J Mech Pays Solids 51 (2003) 1477. The newly built SGP satisfies the non negativity of plastic dissipation, which is still an

Finite Gradient Elasticity and Plasticity

2020
Within the range of finite deformations, material laws have to fulfil certain invariance requirements. If we assume invariance under rigid body modifications, it is generally recommended to use material variables because of their invariance property, i.e. those which are defined in the reference placement.
